To all 'whom t may concern:

Be it known that l, Josnrrr M. OLsoN, citizen of the United States, residing at Canadian, in the county of `lrleinphill and State of Texas, have invented certain new and useful improvements in 4Fasteners for itfindow-Screens, of which the following is a specification. y

rlhe especial object of the improvements embodied in this application is to provide a fastener for a rolling window `screen of simple and, therefore, economical construction, and so mounted or arranged relative `to the window frame and sash that asthe sash is closed the screen will be coiled within a suitably protectingbox, kand the 4sash 1s locked in the framelagainst the tension of the spring roller.

A further object of my invention is to tions of the window frame sash, the screen being removed in order to more clearly illustrate the construction and arrangement of the several parts; Fig. 2 is a cross-section on an enlarged scale taken through one of the stiles of the sash at a point adjacent a catch which is mounted `in the stile andI serves in connection with other features of my device to holdthe screen `in its extended or partially extended relation; Fig. 3 isa vertical transverse section through one of the metal sash bars and the socket in which it is secured when in operative position.

Referring to the details of the drawing, et represents a glass pane set in the usual manner in a sash composed of theusual side and cross members e?. Formed in the stiles da, and along the inner and side faces thereof, are rabbets ab, which extend preferably the entire height of the sash, said rabbets being rectangular in cross-section, as clearly indicated in Fig. 2, and for a purpose to be hereinafter described.

5 represents the side members of an ordinary window frame equipped with the usual stops 6 on the inner sides thereof and supplied with the usual sill 7.

l2 represents two iron rods which are preferably/f rectangular in cross-section and are adapted to iit snugly in the rabbets lb in the opposite stilcs la of the sash. The lower ends of these rods are rounded and threaded externally as atla, to engage the internally threaded socket plates 13, which arelaid into suitable recesses formed in the upper face of the window sill 7 at points just behind the stops 6, and are secured in place by screws 13a, as indicated in Fig. 3. At intervals,` recesses 12b are formed in the rods l2 the walls of which taper inwardly and gradually from the inner face of said rods until they reach the circular sockets 12C, in which the tapered recesses merge as clearly shown in Fig. 3. The stiles of the sash are equipped with the well known forni of yielding bolt latch la, the extended tongues of which are adapted to slide in the recesses 12b, and enter the sockets l2c as soon as the bolts reach the position opposite said sockets. f

. Having thus described my invention, what l claim as new, is

A sash fastener comprising sockets adapted to be secured to a window frame, vertically disposed rods detachably connected with said sockets, said rods having shouldered recesses therein and catches adapted to be mounted upon the window sash for engaging recesses in said rods, substantially in the manner set forth.
